Lawyer Rankings(Leading individuals: Quebec)
McCarthy Tétrault fields an impressive national dispute resolution practice, praised for its ‘exceptional bench strength and business advisory skills‘. It has one of Ontario’s leading litigation departments, which is renowned for handling precedent-setting matters, and appearing before all levels of court and tribunals across the country. A recent highlight saw the team defending Unity Health Toronto in its high-profile C$300m lawsuit with Zurich Insurance. This was co-led by the ‘exceptional‘ Sarit Batner, one of the Toronto office’s standout partners, where securities-focused R Paul Steep is another partner to note. Arbitration is also a strength of the team, and Junior Sirivar is a key contact in that respect, acting in international arbitrations, with sector strengths including mining, banking, telecoms and healthcare. The group in Vancouver is well known for its work in the mining and energy sectors, as well as in cases involving environmental law and Indigenous rights. Jill Yates leads the team there and heads the national class action group, while Michael Feder is a leading name in the market, ‘terrific both at trial and on appeal‘. The team looks to have a bright future ahead with Miranda Lam building a strong commercial litigation practice and expertise in the retail sector, and Aidan Cameron noted for construction and insurance coverage matters. Patrick Williams also stands out at the associate level. The practice in Quebec has gone from strength to strength, led by professional liability expert Steeves Bujold. Mason Poplaw and François Giroux frequently act as lead counsel on some of the province’s standout disputes, and the team is one of the market leaders for insolvencies and class actions. Michel Gagné and Isabelle Vendette are further key figures, as is Emmanuelle Poupart in medical law disputes. In Alberta, the team is led by Douglas Yoshida and other key contacts include expert in the natural resources sector Sean Smyth, and Kara Smyth who also has an impressive practice and was involved in a number of major cases during 2020 and 2021.
